The boundary that separates two different air masses.
What is a front.
100
The name of a breeze blowing from the ocean towards land as warm air rises from the sand and cools and sinks over oceans.
What is sea breeze
100
A winter storm that has winds exceeding 56 km/h and temperatures lower that 27 C with falling or blowing snow that reduces visibility.
What is a blizzard.
100
When warm air rises, it expands and cools. The cool air is unable to hold as much water vapor so the vapor clings to pieces of dust or gas that are floating in the air. This is how __________ are formed.
What is the formation of clouds
200
The average weather usually taken over a 30-year time period for a particular region and time period.
What is climate.
200
This type of front occurs when a cold front catches up to a warm front and the warm front gets caught in between and rises quickly
What is an occluded front.
200
What causes the differences in air pressure on Earth?
What is the variation of temperature caused by unequal heating.
200
A huge rotating storm with wind speed exceeding 75 mph
What is a hurricane.
200
This type of cloud is puffy and looks like a floating cotton ball. They can grow upward and can develop into a giant cumulonimbus cloud
What is a cumulus cloud.
300
This type of weather measuring instrument measures atmospheric pressure.
What is a barometer.
300
This type of air mass originates in a tropical area over water.
What is a mT air mass.
300
The process that keeps heat radiation from the sun near the Earth's surface and allows the Earth to stay warm because the atmosphere keeps the heat within the Earth.
What is the greenhouse effect.
300
This type of sever weather is composed of one or more cells that brings heavy precipitation and strong gusty winds.

What is long periods of cloudy weather.
400
In the troposphere what happens to temperature as the altitude (height) increases.
What is the temperature decreases.
400
This type of weather is characterized as a mobile, destructive vortex of violently rotating winds at immense speeds that have the appearance of a funnel-shaped cloud and advancing beneath a large storm system.
What is a tornado.
400
This type of weather is predicted when cirrus clouds are present.
What is fair/good weather.
500
This system is formed when an air mass cools and flows into an area of lower pressure causing dry and clear skies.
What is a high pressure system.
500
This type of front is characterized by a drop in temperature and thunderstorms.
What is a cold front.
500
Weather is formed due to this phenomenon.
What is the unequal heating and cooling of the Earth.
